José Maria Soberanes (1753-1803) was only 16 when he accompanied the
Portola expedition to San Francisco Bay in 1769. Soberanes married Maria Josefa Castro (1759-1822) and retired from the military in 1795, and with his father-in-law, Joaquin Ysidro de Castro, received Rancho Buena Vista. Soberanes died in 1803 and his widow Maria Josefa Soberanes moved to
Monterey with her sons Feliciano Soberanes (1788-1868) and Mariano Soberanes (1794-1859). Rancho Buena Vista was abandoned. The rancho was regranted José Mariano Estrada and his son, José Santiago Estrada, by Governor
Pablo Vicente de Solá in 1822. José Mariano Estrada (1784-), a Lieutenant of Mexican Artillery, came to California with his brother, José Raimundo Estrada (1784-), in 1797 with
José Joaquín de Arrillaga. Mariano Estrada was the grantee of the two square league Rancho Buena Vista in 1822, and the two square league
Rancho Llano de Buena Vista in 1823. Mariano Estrada married Maria Isabel Argüello who was the daughter of
José Darío Argüello. Their son, José Ramón Estrada (1811-1845), was the grantee of
Rancho El Toro and
Rancho San Simeon. Another son, Julian Estrada (1813 – 1871), was the grantee of
Rancho Santa Rosa. A daughter, Josefa Estrada, married Rafael Gomez (1784-1838), grantee of
Rancho Tularcitos. With the
cession of California to the United States following the
Mexican-American War, the 1848
Treaty of Guadalupe Hidalgo provided that the land grants would be honored. As required by the Land Act of 1851, a claim for Rancho Buena Vista was filed with the
Public Land Commission in 1852, and the grant was
patented to José Santiago Estrada in 1869. In 1872,
Hiram Corey leased the Buena Vista ranch of keeping 450 to 500 cows on the ranch. In 1891, he purchased of the ranch, renaming the property the
Rancho Las Palmas. ==Historic sites of the Rancho==
